Why does the file server cut speed?

Question

Active Directory

There is a windows server 2008r2 server. It has the domain controller and file server roles installed. There are shared folders on the server. There is a laptop with ssd windows 7. Not included in the domain. Logs in under a domain account.
Experiment 1.
While on the laptop, I copy files from the server to the laptop. Speed ​​30 meters.
Experiment 2.
While on the server, I copy files from the server to the laptop (the folder is shared there). Speed ​​100 meters.
The file server cuts speed to users of the domain? How to overcome this problem?

Answer 1

Everything is simple. An SSD drive has a higher read/write speed than a server drive. Therefore, when you copy TO the server, everything rests on the performance of the server's hard disk. And when you copy From the server, then for the server it is already a read operation, which has a higher speed than the write operation, and plus it is not limited by the write speed on the laptop.
A little chaotic, if it's not clear, ask )))
UPD: by default, the file server does not cut speed and there are no such policies by default either.
